Potential critical sources of error in the analysis of microcharcoal in Greenlandic palynological samples – an initial study
Abstract It is common practice to count charcoal particles alongside pollen and non‐pollen palynomorphs in palynological samples. The classification of material as charcoal is dependent upon a number of morphological criteria which, in certain geological zones, could be misclassified. In a prelimina...
